The limitations existed to avoid false + positives when detecting .lzma files. The lc + lp <= 4 limitation + still remains since liblzma's LZMA decoder has that limitation. + + NOTE: xz's .lzma support or liblzma's lzma_auto_decoder() are NOT + affected by this change. They still consider uncommon .lzma headers + as not being in the .lzma format. Changing this would give way too + many false positives. + + * xz: + + - Interaction of preset and custom filter chain options was + made less illogical. This affects only certain less typical + uses cases so few people are expected to notice this change. + + Now when a custom filter chain option (e.g. --lzma2) is + specified, all preset options (-0 ... -9, -e) earlier are on + the command line are completely forgotten. Similarly, when + a preset option is specified, all custom filter chain options + earlier on the command line are completely forgotten. + + Example 1: "xz -9 --lzma2=preset=5 -e" is equivalent to "xz -e" + which is equivalent to "xz -6e". Earlier -e didn't put xz back + into preset mode and thus the example command was equivalent + to "xz --lzma2=preset=5". + + Example 2: "xz -9e --lzma2=preset=5 -7" is equivalent to + "xz -7". Earlier a custom filter chain option didn't make + xz forget the -e option so the example was equivalent to + "xz -7e". + + - Fixes and improvements to error handling. + + - Various fixes to the man page. + + * xzless: Fixed to work with "less" versions 448 and later. + + * xzgrep: Made -h an alias for --no-filename. + + * Include the previously missing debug/translation.bash which can + be useful for translators. + + * Include a build script for Mac OS X. This has been in the Git + repository since 2010 but due to a mistake in Makefile.am the + script hasn't been included in a release tarball before. + + 5.0.4 (2012-06-22) * liblzma: |
